Determination of combined effect of amplification and attenuation of soft rock site using digital seismic data

Abstract

In the paper, for the application of stochastic simulation of ground motion, we put forward a method to determine “the combined effect of amplification and attenuation” (combined effect for short) of soft rock site by using digital seismic data of moderate and small earthquakes. Our approach aims at solving the problem of the combined effect of soft rock site, which is difficult to determine in most regions of China because fewer measures were done for S-wave velocity structure. The combined effect of soft rock site can be determined by using the approach recommended by us. An example is given to discuss the practical application of the method.
